Specification of Letters Patent.

Patented Sept. 21, 1915.

Application filed January 27, 1912. Serial No. 673,760.

To all whom it may concern.

Be it known that I, ELMER L. KNOEDLER, a resident of Gloucester City, in the county of Camden and State of New Jersey, have invented a new and useful Improvement in Packing-Boxes for Mantles, &c., of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a longitudinal section of a packing box embodying my invention, and showing a gas mantle supported therein; Fig. 2 is a plan view of the box with the cover removed; and Fig. 3 is a perspective view of the ring removed.

My invention has relation to packing boxes, more especially designed for packing inverted incandescent mantles, but which can also be used for other articles.

The object of my invention is to provide a box of this character which can be easily and cheaply made, which will permit the mantle to be quickly and readily packed and unpacked, without danger of injury thereto, and which will obviate the use of glue or other fastenings for securing the supporting member in the tube or casing of the box.

A further object is to provide a supporting ring which will exert a shaping or reshaping action upon the tube or casing.

Referring to the accompanying drawings, in which I have shown the preferred embodiment of my invention, the numeral 2 designates the tubular body of the box which may be of any suitable material, preferably paper or pasteboard, and which is provided with the usual bottom 3 and removable cover 4. 5 designates a supporting ring within the upper portion of the tubular body 2. This ring is made of any suitable material, preferably metal, formed by drawing and stamping, one edge portion of the ring being slightly turned outwardly, as shown at 6, and crimped and corrugated'to form a plurality of projecting points, and the other edge portion of the ring being turned inwardly, as shown, to provide a supporting flange 7 for the legs of the mantle ring 8.

The ring can be pushed freely into the tubular body, from the bottom end thereof before the bottom 3 has been inserted and secured; but the engagement of the projecting points with the walls of the body holds the ring against displacement when seated. If desired, however, instead of depending solely upon the frictional engagement of each of the points, the ring can be expanded or punched into more positive engagement with the tubular body.

The flange or ring 7 is preferably so shaped as to have a smooth rounded inner corner which will prevent damage to the mantle, and also a rounded outer corner, so that it will more readily pass into the tube, particularly when starting the insertion.

The rings are preferably of greater rigidity than the material of which the tubular bodies 2 are usually composed, so that when they are inserted within such bodies, they exert a shaping or reshaping action thereon,

bringing the bodies back to approximately true cylindrical form. These tubular bodies are very apt to become misshaped or deformed in handling or from unequal drying after being labeled, and heretofore it has been necessary to throw away large numbers of such boxes, owing to this fact. By reason of the reshaping action of the ring herein described, many of the boxes heretofore thrown away can be redeemed and utilized. The holding of the tubular members to their true cylindrical form insures the proper centering of the supported mantle therein, and prevents contact between the mantle and the walls of the body especially in inserting and removing the mantle from the box.

I claim:

1. A packing box for mantles, comprising a tubular casing having an inserted mantle supporting ring, said ring having an outer friction surface provided with means to operatively engage the casing in one direction of movement but to permit free movement in the opposite direction.

2. A packing box for mantles comprising a tubular casing having an inserted mantle supporting ring, said ring having a downwardly extending flange, outwardly turned portions which friction ally engage the inner surface of the casing Copies of this patent may be obtained for five cents each, by addressing'the Washington, D. 0.?

said flange having and hold the ring in place; substantially as 10 ELMER L. KNOEDLER.
